Are you sure? Because at least in the conservative spheres I pay attention to (admittedly of the less populist variety) almost no one opposes skilled visa expansion. All the light and heat is about legalization. I get the impression that if President Obama went on TV tomorrow and said "Comprehensive immigration reform is a bridge too far right now. Let's simplify and expand the process of legal immigration for skilled workers", then he'd have a bill on his desk in a week.
